When running a large simulation case or a case involving a lot of constraints (boundary conditions, etc.), POLYFLOW may be aborted before the first iteration with the error message “Number of coefficients exceeded !”. In most cases, this can be circumvented by entering (or modifying) an option in the .p3rc file. If running in POLYMAN, select the simulation and click on Tools > Options > Polyflow. In the box that appears, under “Modify .p3rc configuration file”, add the keyword MCONTR30 If running in Workbench environment, right click on Solution cell and click on Preferences > Polyflow. In the box that appears, under “Modify .p3rc configuration file”, add the keyword MCONTR30 If running simulations in standalone mode, then create a .p3rc file containing the keyword MCONTR30 and launch the POLYFLOW calculation with the command polyflow –s .p3rc output.lst The factor ’30’ is indicative and can be increased if the message ‘Number of coefficients exceeded!’ still appears. Then, run the calculation again.
